基于块体理论的边坡稳定性评价及加固优化

Slope Stability Evaluation and Reinforcement Optimization Based on Block Theory

结合汶川地震灾区典型边坡工程的开挖过程,应用块体理论、矢量分析和组合论,在对岩体结构精细描述的基础上,建立了复杂地质模型,运用块体理论分析了各块体在天然、地震和爆破工况下的稳定性,并对加固锚杆的长度进行了合理优化。

Combined with excavation process of typical side slope engineering in Wenchuan Earthquake affected areas, this paper establishes complex geological model with block theory, vector analysis and combinatorial theory on the basis of the detailed description of rock mass structure, and analyzes the stability of each block under the effect of nature, earthquake and blasting with block theory as well as makes reasonable optimization for the length of reinforced rock bolt.
